The ruleIT methodology

SSE10-1

Modern living environments are increasingly supported and guided by software-based systems. IT ecosystems consist of a wide variety of different technical and socio-technical components and subsystems. Many are controlled by software as autonomous agents. However, humans and IT subsystems interact heavily and unfold emergent behaviour that cannot be anticipated or controlled by traditional engineering approaches.

In this document we sketch the fundamental ideas of a software engineering methodology that is tailored for building and maintaining components of a balanced IT ecosystem. This methodology starts at tailor-made techniques for eliciting feedback and requirements in the interconnected environment of an IT ecosystem. Some of the constraints and requirements are transformed into rules.

Those rules guide architectural decisions and model-based software development. In particular, rules enable verification and validation of actual vs. desired behaviour. Since an IT ecosystem is highly dynamic, an equilibrium may always shift or break apart. Runtime verification of behaviour against rules can help to watch for unwanted effects.

This methodology description is an overview rather than a detailed in-depth discussion of all possible development trajectories. We emphasise the importance of involving human stakeholders - and the essential role of rules to create a new software development approach. To illustrate the interaction and combined benefit of all our research aspects, a SmartAirport check-in example is investigated. It is an integral part of the overall Smart Airport example of the IT ecosystem project. Further work in requirements, architecture, and model-based verification will use this overview document for orientation and guidance.
